 <p class="topic">Known bugs and limitations in MultiPowUpload</p>
<br>
All of the specified  bugs and limitations below are related to Adobe Flash API and cannot be fixed by us. We hope there will be some changing in in the next versions of Flash player. 
<ul>
<li>Starting from  version 10 of Flash player,  security reasons do not allow to show file Browse() dialog in Java Script, so it is impossible to make 100% clear HTML + Java Script Interface.
  <br />
  Workaround: MultiPowUpload can run in a hidden mode with transparent UI. In this mode MultiPowUpload can be placed over any html object on a page and  the browse dialog will be displayed by clicking on it.<br />
  Read more <a href="Tutorial.html#hidden">here</a>.

<li>If <code>uploadUrl</code> parameter contains a full URL to the script, you need to have <a href="CrossDomainSecurity.html">crossdomain.xml</a> file in the server root.
<li>To upload files using <strong>SSL (HTTPS)</strong>, uploadURL parameter should have the following format: <code>uploadURL=http://www.yoursite.com:443/uploadfiles.aspx</code>. 443 is port of SSL.
 <li>Flash in non-IE browsers do not pass <strong>cookies</strong> during upload. <strong>Sessions</strong> are different on a page with Flash and upload script.
   <p style="padding-left:15px;">
	Workaround: MultiPowUpload sends cookies and session ID in &quot;MultiPowUpload_browserCookie&quot; Form filed value, but on server side you need some code that parses this value and sets  Cookies collection. MultiPowUpload includes  ASP.NET (Global.asax) and PHP samples.<br /> 
	<br />
   Note: This <strong>bug is not present</strong> if chunked <a href="Tutorial.html#chunk">upload mode</a> used. </p>
<li>Flash Player does not offer complete support for servers that require <strong>authentication</strong>. Only SWF files that are running in a browser using the browser plug-in or Microsoft ActiveX&reg; control can provide a dialog box to prompt a user to enter a user name and password for authentication, and then only for downloads. For uploads using the plug-in or ActiveX control or upload/download using either the stand-alone or external player, the file transfer fails.
  <p style="padding-left:15px;">Workaround: No.</p>	
<li>Impossible to get <strong>path of selected or uploaded file</strong>. Only file name is available. Filename property also includes only file name without path in the upload script .
  <p style="padding-left:15px;">Workaround: No</p>
<li>Content-Type for all uploaded files is <strong>"application/octet-stream"</strong>.
<p style="padding-left:15px;">Workaround: Read file extension to get types of files.</p>
<li>Flash sends files only one by one:  each file is in a separate request.
  <p style="padding-left:15px;">Workaround: No.</p>
<li>File processing script (that is specified in uploadUrl parameter) should  send at least one symbol to response. Otherwise, onComplete event does not occur in <strong>Safari (Mac OS) browser</strong>, therefore only the first file will be uploaded.
  <p style="padding-left:15px;">Workaround: No.  </p>
</ul>
